The RPQ2 preamp provides two channels with 81dB of sweet JFET gain and super high input impedance of 63K Ohms delivering the precision, quietness, and headroom needed for today's high-resolution recordings

The TRP (The Ribbon Pre) is an ultra high gain and high impedance, minimal-path FET microphone preamp designed by Fred Forssell. The TRP started a new movement in preamp design that specifically addresses the needs of ribbons.

The RPQ500 module, designed after the successful RPQ preamp, provides the same ultra-clean, high-gain signal path that has earned AEA preamps their great reputation, but in a 500 series package. JFET circuit topology provides all the dynamics, subwoofer bass, and fast transients
